NOTE
When POWER rocker switch is pressed to ON, TI
automatically performs a self-test sequence. Upon successful
completion of self-test, TI will be in normal operating mode.
b. Press POWER pushbutton to ON and allow at least 20 minutes for equipment to
warm up.
NOTE
Perform dc adjustment checks c through u below for both CH 1
and CH 2. When performing CH 2 adjustments, add the
number 200 to all resistor and capacitor references. For
example referenced in step g below for CH 1 is R253. When
performing the same procedure for CH 2, the resistor would be
R453.
NOTE
When performing CH 1 adjustments, TP 4 is referenced; when
performing CH 2 adjustments, TP 11 needs to be referenced.
When performing CH 1 adjustments, TP 2 is referenced; when
performing CH 2 adjustments, TP 9 needs to be referenced.
c. Short rear panel CH 1 INPUT.
d.
Press MODE parameter key until
CUTOFF FREQUENCY display indicates h.P.
e. Press OUTPUT GAIN(db) ∆ control key until display indicates 20.
f.
Connect digital multimeter to
rear panel CH 1 OUTPUT.
g.
Adjust DC ADJ
R253 (fig. 2), located to the right of
rear panel CH 1 OUTPUT BNC
connector for digital multimeter indication of 0 V dc 1 mVdc.
h. Press OUTPUT GAIN(db) ∇ control key until display indicates 00.
i.
Adjust R268 (fig. 2) until
multimeter indicates between 0 V dc 1
mVdc.
j.
Repeat e and g above.
k. Repeat h and i above.
